While not exhaustive, here's what I found:

DMC4 global sales totaled 2.76 mil.

Devil May Cry HD Collection totaled about 0.8 million worldwide.

DmC: Devil May Cry has, so far, fared even worse at just under 0.7 mil. globally. http://www.vgchartz.com/gamedb/?name=DmC%3A+Devil+May+Cry&publisher=&platform=&genre=&minSales=0&results=200
